Application filed December 21, 1915. Serial No. 67,978.

To all whom it may concern: a J

Be it known that l, FRANZ Sriirm, sub ect of the German Emp'eror,'and resident of Essen-on-the-Ruhr, in the Province of the Rhine, Germany, have invented a certain new and useful Apparatus for Forming Parallel Faces on the Ends of Adjacent Elements, Such as Railway-Rails,'of which the following is a specification.

This invention relates to apparatus for forming parallel faces on the endsof adjacent elements, such as railway rails.

Before the adjacent ends of railway rails are welded, it is essential that the. adjacent faces be cut to exact parallelism. The present invention aims to provide a simple and eiiicient form .of apparatus for accomplishing this, the apparatus being especially designed for carrying out the method disclosed in the prior Patent, No. 1,154,918, of September28, 1915. The method disclosed in the above-mentioned patent consists in recipro eating a so-called double inclined edge cutting tool between the adjacent faces of the railway rails or other objects to be buttwelded, and in feeding the tool during its reciprocation through the objects until the surfaces are cut to substantial parallelism. The present apparatus comprises means for reciprocating such a cutting element between the ends of the objects to be buttwelded and means for feeding the cutting element through the objects during the reciprocation of the cutting element.

The invention is illustrated in the accom-' panying drawing, in whichz- Figure l is a side elevation of the improved apparatus showing the same supported upon the adjacent ends of two railway rails; Fig. 2 is a vertical section taken on the line 22 of Fig.1; and Fig. 3 is a horizontal section taken on the line 33 of Fig. 1. j

Referring to the drawing, it will be seen that the apparatus comprises an oscillatory levenA which is pivoted at a point intermediate its ends to a suitable support or clamp B capable of being applied to the rail ends to support the lever A in operative relation with respect to the surfaces to be treated. The extreme lower end of the lever A has associated therewith a cutting head C for carrying the cutting elements, The extreme up per end D of the lever A is adapted to be grasped by the hand of the operator to oscillate the lever, and hence reciprocate the lower end C of the lever.

The lever A is formed in two sections, one of which telescopes within the other. The upper section of the lever A is shown at 1, and the lower section is shown at 2. The upper end of the lower section 2 telescopes in a central longitudinal opening 3 formed in the upper section 1. As best-shown in Fig. 3, the cross section of the lower section Patented ma as, rare. I

2 is substantially square in shape to prevent said lower section from turning in the upper section 1. As a means to hold the lower section in firm connection with the upper section and take up wear of the parts, the upper section at its lower end is enlarged, as shown at 17 (Fig. 2) and formed with a transverse opening extending completely therethrough to receive wear blocks 14:, 14, for engagement with the upper section at opposite sides thereof as shown. As best shown in Fig. 3, the wear blocks 14, 1 1- are in the nature of integral projections formed on plates 15, 15. The blocks 14 are inserted in the aforesaid transverse opening and are removably held in place by securing the plates 15 to the lever. This is accomplished by means of screws 16, there being one screw at the top and one at the bottom of each plate, as shown in Figs. 1 and 3, to enter the solid portion of the lever above and below the transverse opening.

The upper portion D of the lever A constitutes'a handle which is rotatably mounted upon the upper section 1. This handle D carries a rod 4, which passes downwardly through the section 1 and is adapted to turn therein. The lower portion 5 of the rod 4 is threaded and is received by an internally threaded opening "in the lower section 2. By this means, it is obvious that when the handle I) is turned, the section 2 will be tremities The pivot screws 7 may be locked in their adjusted )0S1ti011 by means of the lock nuts 10.

The support B is so shaped as to be prop- When so applied to the rail ends and adjusted thereon to bring the lower end 0 of the oscillatory lever in proper position with respect to the surfaces to be treated, the support may be clamped in position by means of the clamp screws 11.

The cutting head C is adapted to receive oneor more cutting elements, shown at 12, which are inserted in the cutting head and clamped therein by means of the bolt 13.

When it is desired to form parallel faces on the ends-of railway rails by the apparatus above described, the support B is aplied to the rail ends in such a manner as to bring the lower extremity of the lever A, or, in other words, the cutting head G, as nearly as possible in proper position with respect to the faces of the rail ends. The clamp screws 11 are then tightened to rigidly hold the support B upon the rails. The clamp nuts 10 are then loosened and the pivot screws 7 are adjusted to obtain the final adjustment of the cutting head. The, cutting head should be so adjusted by the pivot screws 7 that the cutting elements 12 will cut substantially equal amounts from the two rail ends. The lock nuts 10 are then tightened and the apparatus is in readiness for operation.

The ap aratus is operated by grasping the handle and imparting an oscillatory movement tothe lever A, as indicated in Fig. 2.- This will reciprocate the cutting head C in an arc of a circle between the rail ends. By imparting turning movements to the handle D during the oscillation ofthe lever A, the cutting head C may be fed downwardly between the rail ends. The combined reciprocating movement of the cutting head G and downward movement thereof will cause the cutting elements 12 to cut a portion from the end of each rail. As the apparatus is so constructed that the cutting head C is fed downwardly, it'is obvious that when the cutting operation is first started, the-cutting head C is raised to start the cut atthe tread of the rail. In Fig. 1', the cutting head C is shown as having been fed half way down between the rail ends.

The present apparatus is designed to place the ends -of the rails in condition to be welded by cutting the ends to exact parallel newer ism and by forming bright surfaces on the ends of the rails. The rough cut may be made in the rails to form the welding opening by any appropriate apparatus desi ed for the purpose, if it is necessary to pre 1minarily out the rail ends before the present finishing apparatus is used.

It is obvious that the apparatus above described may be constructed in various other ways than that herein disclosed without departing from the spirit or scope of the invention, as defined in theaccompanying claims. I r v What I claim is I 1. Apparatus for forming parallel faces on the ends of adjacent rallway rails and the like comprising an oscillatory lever, oppositely projecting cutters rigidly carried by the lower end of the lever so as to oscillate therewith, means to pivotally support the lever intermediate its ends in such a manner as to bring the oppositely projecting cutters into operative relation with the rail ends, and means whereby said cutters may be fed longitudinally of the lever and between the rail ends during the oscillation of the lever.

2. Apparatus for forming parallel faces on the ends of adjacent railway rails and the like, comprising an oscillatory lever composed of two telescoping parts, means to pivotally support the lever to bring a portionof one of the parts of the lever into operative relation with the rail ends, a cutting element associated with such portion of one of the parts of the lever, and means for feeding that part of the leverwhich carries the cutting element out of the other part of the lever during the oscillation thereof to feed the cutting element between the rail ends, for the purpose described.

3. Apparatus for forming parallel faces on the ends of adjacent railway railsand the like, comprising. an oscillatory lever pivotally supported intermediate its ends to bring the lower end of the lever into operative relation with the rail ends, a cutting element associated with the said lower end of the lever, a rotary handle at the upper end of the lever whereby the lever may be oscillated, and means whereby the rotation of said handle during the oscillation of the le ver feeds said cutting element between the rail ends during the oscillation of the cutting element, for the purpose described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
